Hydraulic Rotary Excavator Swing Motor Assembly JMF29 DH60 Machinery Parts

The role of the rotary motor

The rotary motor is a key component of the slewing mechanism, which converts the oil pressure provided by the main pump into mechanical energy and enters it to the gearbox. The quality of its working performance will directly affect the swing speed, driving torque, swing stop and parking brake of the whole machine, which is the key to determining the productivity of the whole machine.

Slewing motors are divided into two egories: low-speed large-torque motors and high-speed rotary motors.

Low-speed large torque motor is rarely used in the slewing mechanism of modern excavators due to its large size and heavy mass, while the high-speed slewing motor is small in size and light in weight, which is convenient for the reasonable layout of the slewing mechanism and can also meet the requirements of different slewing speed and torque, so it is widely used.

After a long time of work of the excavator, the slewing motor of the slewing mechanism often has weak rotation and unstable rotation. Causes and countermeasures
